COI1685E Microchannel Condenser Coil E-Coat

Code: COI1685E
E-Coat Microchannel Condenser Coil COI1685E (RTAF)

Electrocoatings are typically made from polymeric resins, solvents and diluents, and pigments. Resin is a base of the paint which provides protection against corrosion and ultraviolet durability. Pigments and solvents provide coloring, glossing, and smooth appearance of the end product. The nature of the resins for the electrocoating can vary, but any type of resin feature functional groups in the backbone which allows them to become ionic in the presence of neutralizing agents.

Heat exchanger protection with electrocoating

Corrosion, the deterioration of metals and alloys through a physical and/or chemical reaction with the environment, is expensive. Heat exchangers used in HVAC equipment, specifically condenser and cooling/heating coils are exposed in the environment, and this can lead to corrosion, failures, and performance degradation of the equipment in the cases of improper heat exchanger protection in corrosive locations.

Potentially corrosive environments include coastal and marine areas, locations adjacent to industrial and urban areas, locations with proximity to heavy road traffic, factories, power plants, or the combinations of the above.

Unprotected heat exchangers, regardless of their type, are subjected to corrosion. Although all-aluminum microchannel coils tend to be less affected by corrosion compared to copper-aluminum finned-tube coils, the protection must be applied in order to prevent deterioration in aggressive atmospheres. The highest level of corrosion resistance can be achieved with the right coil coating. For microchannel heat exchangers, the best coating option is factory-applied electrodeposition, which is also referred to as electrocoating (e-coating) or electrophoretic deposition, and produce uniform finishing with excellent corrosion resistance.

Advantages Of Electrocoating

Electrocoating offers significant advantages over other coating technologies, including:

  • High corrosion protection. Cathodic epoxy electrocoating with a film thickness of 20 microns withstands more than 1000 hours salt spray test performed in accordance with ASTM B117 standard
  • Uniform coating with no more than 1-2 micron variances across the coated surface of any shape complexity
  • Eco-friendliness: heavy metal free, no hazardous air pollutants (HAPS), low levels of organic solvents, and low volatile organic compounds (VOC)
  • Aesthetic quality
